The table shows the crossing-over frequencies for three genes in the fruit fly Drosophila. The greater the frequency, the more likely that crossing over separates the genes. The gene for eye color (A), wing shape (B), and body color (C) are found on the same chromosome. GenesCrossing-over frequency A and B12.5% A and C6% B and C18.5% What are the two most likely sequences of these genes on a gene map for this chromosome? Select two options. A. B, A, C B. A, B, C C. C, B, A D. C, A, B

a is my answer hahahaha i had to do that for it work

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
